PBES2 Password-Based Encryption

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Dim crypt As New Chilkat.Crypt2

// Set properties for PBES2 encryption:

// When the encryption algorithm is set to "pbes2",
// Chilkat will automatically derive the actual secret key using PBKDF2 and
// the specified paramters: password, salt, iteration count, hash function, and desired key length.

crypt.CryptAlgorithm = "pbes2"
crypt.PbesPassword = "mySecretPassword"

// Set the underlying PBE algorithm (and key length):
crypt.PbesAlgorithm = "aes"
crypt.KeyLength = 256

crypt.SetEncodedIV "000102030405060708090A0B0C0D0E0F","hex"

// Give it some salt:
crypt.SetEncodedSalt "0102030405060708","hex"

// A higher iteration count makes the algorithm more
// computationally expensive and therefore exhaustive
// searches (for breaking the encryption) is more difficult:
crypt.IterationCount = 1024

// A hash algorithm needs to be set for PBES2:
crypt.HashAlgorithm = "sha256"

// Indicate that the encrypted bytes should be returned
// as a hex string:
crypt.EncodingMode = "hex"

Dim plainText As String
plainText = "To be encrypted."

Dim encryptedText As String
encryptedText = crypt.EncryptStringENC(plainText)

System.DebugLog(encryptedText)

// Now decrypt:
Dim decryptedText As String
decryptedText = crypt.DecryptStringENC(encryptedText)

System.DebugLog(decryptedText)
